Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139002, here are decompositions:

43 + 138959 = 139002
79 + 138923 = 139002
103 + 138899 = 139002
109 + 138893 = 139002
113 + 138889 = 139002
139 + 138863 = 139002
173 + 138829 = 139002
181 + 138821 = 139002

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 139,002 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
